OAKLAND (KTVU & AP) -- Fire tore through an Oakland warehouse converted into artist studios during a late night dance party Friday night, killing at least nine people, and officials said Saturday that the death toll could rise as high as 40.
At least nine people have been confirmed dead, but Alameda County sheriff's Sgt. Ray Kelly said "we expect the death toll from this event to rise," with at least a couple dozen people unaccounted for. At a press conference at 6 p.m., Kelly said "several dozen unaccounted for people have been found" but he added that officials have begun the process to identify the victims.

Four of the confirmed nine people who died have been recovered from the scene as of 4 p.m., Kelly said.
Authorities will be using heavy equipment to breach the building at points other than the front entrance, which is blocked with debris, Kelly said.
He described the scene as "like a maze" with wreckage from the roof that collapsed onto the second floor, which collapsed onto the first floor.
Officials said people either escaped from the cluttered building or died inside, where the only way down from the second story was via a stairwell constructed entirely of wooden pallets.
"It appears that either you got out or you got trapped inside," Kelly said.
Firefighters used chain saws and axes Saturday to cut through the debris of the cluttered building in a gritty neighborhood of this San Francisco Bay Area city, where the fire broke out about 11:30 p.m. Friday.
Oakland fire chief Teresa Deloche-Reed said Saturday at least another 25 people were unaccounted for in what authorities were calling the most deadly building fire in the city in recent memory. The victims were believed to be young people in their 20s, Kelly said. He said as many as 40 may have perished and that the coroner is preparing for a "mass casualty event" that could include victims from other countries.

The warehouse was known as the "Oakland Ghost Ship." Its website showed pictures of a bohemian, loft-like interior made of wood and cluttered with rugs, old sofas and a garage-sale like collection of pianos, paintings, turntables, statues and other items.
The website included advertisements for various electronic music parties. On Friday night, there was an event featuring musician Golden Donna's 100% Silk West Coast tour.
Panicked friends and family posted messages on the group's Facebook page trying to find out if their loved ones were among the dead. Those searching for the missing were sent to a local sheriff's office, where Dan Vega was anxiously awaiting news. He had been unable to find his younger brother or his brother's girlfriend. Vega said he was not sure if the two were at the party Friday night but that his brother likes to go to raves and he had not been able to reach him Saturday. His girlfriend's car was still parked at a transit station in San Bruno, south of San Francisco.
Fighting tears, Dan Vega said he's frustrated authorities hadn't been able to tell him anything about his 22-year-old brother.
"I just want to go over there. I have my work boots on, I'm ready to go," Dan Vega said. "Just give me some gloves. I'll help out any way, shape or form, I don't care. This is infuriating. I don't know where my brother's at. I just want to find him."
It was not immediately clear what started the fire, but there did not appear to be sprinklers in the building, Deloche-Reed said. She said 50 to 100 people were believed to have been at the party when the fire started and that clutter "made it difficult for people to escape."
The warehouse was partitioned into artist studios and was packed with furniture, mannequins, statues, lamps, and other objects and did not have a clear entry or exit path, the fire chief said.
"There is still a large portion of the building that still needs to be searched," she said. "There is large timber and debris that will need to be removed and it's going to have to be removed in a slow and methodical way."
The fire caused the building's roof to collapse and investigators were having trouble entering parts of the warehouse to search for any remaining bodies because the structure was deemed unsafe, Deloche-Reed said.
One survivor said he struggled to find a working fire extinguisher.
"It was too hot, too much smoke, I had to get out of there," Bob Mule, a photographer and artist who lives at the building and suffered minor burns, told the East Bay Times. "I literally felt my skin peeling and my lungs being suffocated by smoke. I couldn't get the fire extinguisher to work."
Oakland police urged those concerned about missing people to call the Alameda County Sheriff's Coroner's Bureau at 510-382-3000.
The office said coroners were also at the scene Saturday morning and unavailable for comment.
